Camco’s Cold Weather Heated Drinking Water Hose protects the water line from freezing down to -40°F (-40°C) and won’t leach harmful chemicals or leave the water tasting like plastic. The internal diameter of the hose is 5/8-inch, and the fittings are heavy-duty machined and plated for maximum corrosion resistance. The durable exterior PVC jacket protects the water hose and electrical components from damage or exposure. It’s easy-to-use, lead- and BPA-free, includes a female-to-male adapter to allow connection to the water supply on either end, operates on 120VAC and uses an 18AWG 10-foot power cord with LED indicator plug. Available in 12’, 25’ and 50’. See also Camco’s RV Water Heater Drain Plug Kit which fits both 7/8” and 15/16” drain plugs.
